Alright, i'm currently using an ArcSaber 7 with bg68ti at 25x27lbs.( with 4 knots ) Fairly good when it's freshly strung. Since when it's freshly strung, my shots travel faster, sharper and accuracy are better ( might be just my head? ) Then now, after a few days of badminton with the freshly strung Arc7, I found out that my shots are not as fast, as sharp or as accurate as it was. I blame it on the tension that has dropped? Also, I've now ran out of bg68ti and I need to buy new ones. I'm thinking of trying out bg80 but people says it changes tensions quite quickly. So any suggestion? Should I just furtherly increase the tension? or just change string? Thanks.
